I just started playing this and would love to see this supported.
and Sphinx has some of the support already. For example I am using these two extensions for sphinx:
IPython.sphinxext.ipython_directive
This allows me to use .. ipython: and .. code-block: ipython to render out ipython data. To generate rst from the ipython notebook I'm currently running `ipython nbconvert <my notebook> --to rst` and once I have rST I just copy it into my blog post.
What I would like to see provided by tinkerer is built-in support for the nbconvert step. Something like .. notebook: <filename> and have it auto run the convert to get the restructured text and embed it with any images generated.
